APPARATUS FOR COOLING CUBE-SUGAR.

SPECIFIGATION forming part of Letters Patent No. 227,477, dated May 11, 1880.

Application filed December 27, 1879.

To all whom it may concern:

Be it known that I, JOHN V. V. BOORAEM, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Apparatus for Goolin g Cube-Sugar, of which the following is a specification.

Figure 1 is a plan view of theimprovement. Fig. 2 is a sectional elevation taken through the line 50 as, Fig. '1.

The object of this invention is to furnish an apparatus for cooling cube-sugar after it has been dried, so constructed that the sugar may be thoroughly cooled quickly and before the cubes have had time to stick together.

Similar letters of reference indicate corresponding parts.

A represents the joists, and B the floor, of a sugar-refinery. O is the ceiling of the room below'the floor B. The spaces between a number of the joists A are formed into an airchamber, Q, by closing the ends of the said spaces by boards D and securing a communication between the said spaces by attaching a portion of the ceiling G to timbers E, secured to the lower edges of the joists A. If desired, the joists A may be made of iron, and openings may be formed through them to allow the air to pass freely from one part of the airchamber Q to another part without its being necessary to make a downward offset in the ceiling. The chamber Q thus formed is made air-tight by placing pitched felt F, tarred paper, or other suitable material between the parts of the double fioor B, between the parts of the double ceiling O, and in the joints between the timbers A D E. Air is forced into the air-chamberQfrom above or below through a pipe, G, by a fan-blower. In the floorB are formed a number of holes, H, opening into the spaces between the joists A, and to the said floor B, directly over the holes H, are attached circular metal plates, I, which have tapering holes J formed through their centers corresponding with the holes H. Upon the plates I are formed wide and low ring-flanged or raised portions K, the faces of which are faced perfectly true.

L are rubber stoppers, which are tapered to fit snugly into the tapering holes H J. The rubber stoppers L have lead M or other heavy substance attached to them, to hold them securely and air-tight in their places.

N are sugar-receptacles, which may be ordinary wooden barrels or metal sugar-receptacles, as may be desired. The sugar-receptacles N are made with bottoms O of metal or other suitable material, which bottoms are perforated with numerous holes, and have metallic ringflanges, P, formed upon or attached to them. The flange P is made a little higher than the chines of the sugar-receptacle N, and its edge is faced perfectly true, so as to form an air-tight joint with the flange K when the sugar-receptacle N is placed upon the plate I. The flange P must project so much that the chines of the sugar-receptacle will not touch the floor or other level place when the sugarreceptacle is standing upon the flange P, and at the same time the flange P must not project so much as to come in contact with the floor when the sugar-receptacle is being rolled from place to place upon its chines.

The cooling apparatus is designed to be placed between the drying-stoves and the dumping-screen to avoid unnecessary transportation of the sugar-receptacle and sugar.

In using the apparatus the cubes of sugar are emptied from the drying-pans as they are removed from the stoves into a sugar-receptacle, N, and the sugar-receptacle, as soon as it is filled, is rolled to the cooling apparatus and placed upon one of the plates I, the stopperL being first removed, so that the air may be forced up through the perforated bottom 0' and through the sugar, cooling the sugar before the cubes have had time to stick together.

' When the sugar is thoroughly cooled the sugarreceptacle is rolled to the screen, and the suand through the air-chamber Q, the direction of the air being immaterial.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1 1 1. The combination of the floor B, having bottom, 0, carrying a faced ring-flange, I, 15 substantially as herein shown and described, to form a close joint with the flange K of the plate I, as set forth.

4. In an apparatus for cooling cube-sugar, the combination, with the air-chamber Q and the floor B, of the plate I, provided with the faced flange K and the air'exitaperture J, substantially as herein shown and described.

JOHN V. V. BOORAEM.
